A. a need for a longer neck activates the long-neck gene throughout development.
B. the presence of variety among a population works against the advantages of natural selection.
C. in each generation, individual giraffes strain their necks to reach food just a bit higher, and that this straining somehow modifies their genetic material.
D. natural selection works on the genotype, not the phenotype.
E. in each generation, individual giraffes mate with giraffes having longer necks because they are better at getting food, and their offspring's neck size results in an average of the parents' neck sizes.
